Concert Experience for $5k?

Zu Druid Vs would be great as others have mentioned.  Horns are the other idea, but probably out of budget.  

Altec Model 19's

where?tell me:)? I want them too

I just got my hands on a pair of Krell Resolution 2 speakers from Highperformancestereo and I am absolutely mesmerized at how F--kin great these speakers are for all music tastes.  They actually deliver a better experience than my Wilson Sophia's, W/P 6's, Dynaudio C4's or my recent B&W802D2's.  Spectacularly dynamic and soundstage like crazy with no roll off on either end.  I got mine for &3300

almarg, curious about a response of yours. You indicate that in the case of the GET Triton One's the amp wouldn't be a good match because (paraphrasing) the higher amp output impedance and the speaker’s variation of impedance would be an under-emphasis of the mid-bass region, and excessive brightness in the upper mid-range.

Why should the impedance mismatch yield any different sound characteristics in the T1s than if it were paired with an amp whose impedance was an exact (no such thing I know) match? If the impedance of the GE T1s are low with respect to the amps "preferred" impedance, this should manifest itself as additional current being drawn from the amp and not necessarily anything audibly undesirable. Granted, to much current draw is itself undesirable. 

I mix concerts professionally (generally smaller jazz, classical, or folkie stuff) and I can't imagine why anybody would want the "concert experience" in their home. The sound is "dual mono" (with light stereo reverb sometimes to make the crowd think they feel better) because if you used a stereo mix you'd have to make the crowd sit in the middle…uncomfortable to be sure, and although the live show can sound excellent (when I mix it always does), it's a different animal. Louder large shows might provide more bass kick than you're used to at home, but get a sub and that difference is covered, generally with more accurate tone. You don't want 115 db at home unless maybe you're drunk and dancing, in which case a small pro PA system is what you need…along with ear plugs.
